Abstract
We study baryogenesis through lepton number violation in left-right-sy mmetric models. In these models the lepton number and CP-violating out -of-equilibrium interactions of the triplet Higgs scalars can give ris e to lepton number asymmetry. This in turn generates baryon asymmetry during the electroweak anomalous processes. If these lepton-number-vio lating interactions are in equilibrium, they can wash out any primordi al (B - L) asymmetry.
